Exploiting nonequilibrium phase transitions and strong symmetries for continuous measurement of collective observables
A collective spin system is considered, whose constituents aregoverned by a dissipative dynamics that displays a strong symmetry(total angular momentum) in conjunction with a nonequilibrium phase transition. By monitoring the system output, it is shown that these ingredients allow to infer the value of the total angular momentumwithout the need of repeated projective measurements orreinitializations of the spins.
